IMPROVEMENT IN SCRUBBlNG-BRUSHES.

Specification forming part of Letters Patent No. 132,049, dated October 8, 1872.

To all whom it may concern:

Be it known that I, AMOS S. BRINSER, of

Falmouth, in the county of Lancaster and State of Pennsylvania, have invented a new and valuable Improvement in Scrubbing-Brushes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing makinga part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawing isarepresentation of a perspective view of my invention; Fig. 2 is a detail view; Figs. 3 and 5 are details; and Fig. 4. is a vertical section of my invention.

My invention has relation to a floor-scrubbin g utensil, in which a block of India rubber clamped between two parallel plates and secured by bolts is used as the frictional material; and the novelty consists in constructing the front plate of the clamp and the shank which is attached to the handle in one piece,

in making rectangular bolt-holes through said plate to prevent the square-shouldered bolts from turning, and in arranging the back plate, bolts, and India-rubber block, substantially as hereinafter described.

Referring to the accompanying drawing, A represents an oblong rectangular block of India rubber of suitable flexibility for scrubbing purposes.

a a designate holes through said block for the passage of the bolts b. These holes may be in the form of slots, as shown in Fig. 2, to allow the block to be adjusted, according as it becomes worn. B B-designate the clampingplates. The plate B is formed by flattening out the end of the shank O, to which the handle D is attached. The plate B is a separate piece. The India-rubber block is secured between the plates B B by means of the bolts 1) b. These bolts have square shoulders 0 near their heads, fitting squared holes 0 formed in the plate B, for the purpose of preventing the bolts from turning and the plates from becoming loose. On its inner end each bolt holds a nut.

What I claim as my invention, and desire to secure by Letters Patent, is- The improved scrubber having the clamp, consisting of the front plate B formed on the end of the shank O, and furnished with square bolt-holes, the rubberA having elongated slots at a, the back plate B, and the square shankbolts, all constructed and arranged substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two Witnesses. I

AMOS S. BRINSER.
